The Gefjun was an Aesir-class DropShip assigned to the Valkyrie Galaxy, an all-aerospace Galaxy within the Rasalhague Dominion military, in the mid-thirty-second century. By 3145 the Gefjun was one of four Aesirs serving in Valkyrie Galaxy, serving alongside the Balder, Syn and Var; the four ships had been split across the two active Clusters within Valkyrie Galaxy at the time, allowing Valkyrie to rove throughout the Alshain and Rasalhague systems while also providing heavy support.[1]
